TODAY AND TONIGHT OVER THE GULF OF TEHUANTEPEC ALONG WITH
MODERATE TO ROUGH SEAS. BY THU MORNING, GALE FORCE NORTHERLY GAP
WINDS WILL RESUME IN THE GULF OF TEHUANTEPEC REGION DUE TO A
STRONG RIDGE THAT WILL DEVELOP OVER THE GULF OF AMERICA AND
ACROSS EASTERN MEXICO IN THE WAKE OF A STRONG COLD FRONT. FOR
FRIDAY INTO SATURDAY, A STRENGTHENING SURFACE TROUGH WILL BRING
MODERATE TO FRESH E TO SE WINDS AND SEAS OF 6-8 FT TO THE WATERS
S OF 21N AND W OF 110W. ANOTHER ROUND OF GALE FORCE WINDS IS

GALES IN THE GULF OF TEHUANTEPEC ARE IMPACTING THE OFFSHORE
WATERS OF GUATEMALA AND EL SALVADOR. MODERATE OR WEAKER WINDS
AND SLIGHT SEAS PREVAIL ELSEWHERE. A 1008 MB LOW PRESSURE
OFFSHORE WESTERN COLOMBIA IS GENERATING SCATTERED SHOWERS AND
ISOLATED THUNDERSTORMS WITHIN 150 NM OF SHORE.
FOR THE FORECAST, HIGH PRESSURE NORTH OF THE REGION WILL SUPPORT
FRESH TO STRONG NORTHEAST TO EAST WINDS IN THE GULF OF PAPAGAYO
REGION THROUGH THE FORECAST PERIOD, EXCEPT FOR THURSDAY NIGHT
INTO FRIDAY MORNING WHEN STRONG TO LOCALLY NEAR GALE-FORCE WINDS
ARE EXPECTED. PULSING MODERATE TO FRESH NORTHERLY WINDS ARE

THE WESTERN PART OF THE AREA THROUGH THU. ROUGH SEAS IN THIS
REGION WILL GRADUALLY SUBSIDE DURING THAT PERIOD. OTHERWISE, THE
RESIDUAL MODERATE SEAS ASSOCIATED WITH THE GAP WIND EVENT OVER
THE GULF OF TEHUANTEPEC THAT JUST ENDED WILL CONTINUE TO SUBSIDE
TODAY AND TONIGHT BEFORE ANOTHER ROUND OF MODERATE TO ROUGH SEAS
OCCURS WITH THE NEXT TEHUANTEPEC GAP WIND EVENT, IMPACTING
SIMILAR AREAS. A SET OF LONG- PERIOD NORTHWEST SWELL IS EXPECTED
TO BEGIN TO MOVE INTO THE FAR WESTERN WATERS TODAY. ANOTHER SET
OF LONG-PERIOD NORTHWEST SWELL WILL LIKELY ENTER OUR NW WATERS
